"The Police Department, Kamogawa City Police Station and Morimura Middle School have all faxed the list you requested!"

Early the next morning, Lin Xiuyi had just come to the office, and Miki immediately told him the news.

After Lin Xiu heard the news, he didn't immediately go to brew coffee as usual. He actually sat at the desk, which was rare, and carefully compared the names on the list on the side.

Sadly, the two lists do not have any identical names. Lin Xiuyi's guess was denied in an instant.

Lin Xiuyi threw the list on the desk in disappointment, and then got up to play with his coffee utensils.

The jar containing the coffee beans was opened by Lin Xiuyi, and then Lin Xiuyi used a small metal shovel to shovel out some coffee beans and put them on the electronic scale until enough coffee beans were taken out. Lin Xiuyi picked up the filter paper holding the coffee beans on the electronic scale, then put the coffee beans into a small hand coffee grinder, and then patiently ground the coffee powder.

Coffee grounds are not meant to be as finely ground as possible. Only by combining the thickness of the particles and the method of brewing coffee, can the unique aroma of coffee beans be fully extracted. If you combine coffee beans from different tea origins and roasting methods, it will be more complicated. It takes a long time to try to gradually summarize the rules, and its complexity is not at all simpler than the detection of cases. Although Lin Xiuyi's method of brewing coffee seems to be exactly the same every day, the coffee brewed every day has subtle changes. So far, apart from Lin Xiuyi, the only one who can experience this change is the next-door Section Chief Matsuda.

"Good morning, it seems the time is just right!"

Section Chief Matsuda came to the Special Search Department with a coffee cup as usual, while Lin Xiuyi was slowly brewing the coffee powder on the filter paper with a fine-mouth pot. With the addition of hot water, the aroma of coffee powder began to permeate the entire room of the Special Sou Department.

About five minutes later, Lin Xiuyi's special black coffee was brewed. Lin Xiuyi removed the filter paper on the coffee pot, and then poured the pot of coffee into three cups, just enough for three cups. Miki, Lin Xiuyi, and Section Chief Matsuda raised their respective coffee cups on the coffee table at the same time, and then carefully took a small sip to their lips. Until now, Lin Xiuyi felt that the sleeping cells in his body were awakening.

After a cup of coffee, Lin Xiuyi cleaned the coffee utensils and put them back where they were before returning to his seat to work.

The information on the list made Lin Xiuyi's assumption fail again. But this is not an unacceptable result. For criminal investigation, every time a wrong path is proved, the hope of finding the truth next time will be greater. When all wrong paths have been denied, the one that remains is the right path to the truth.

So far, Lin Xiu's situation with the suspects is still not optimistic. But in the vagueness, Lin Xiuyi has already mastered certain information.

The two victims selected by the criminal suspect obviously had certain similarities in character and interpersonal relationship. They were also not good at communicating with their peers and were often bullied at school. It is precisely because of this that criminal suspects are more likely to obtain new appointments from victims.

In terms of modus operandi, criminal suspects also have their own unique set. He did not forcefully take the victim away by violent means like an ordinary kidnapper. Instead, abduction was used to guide the victim to run away from home. And before the final abduction, the suspect will instigate the victim to carry out a small number of thefts. However, these thefts are not for the purpose of money, and are likely to be a method of psychological control of the victims by the suspects.

In addition to the premise that the above points are relatively large, Lin Xiu has an unconfirmed speculation about the suspects, that is, the suspects may have a certain connection with the University of Tokyo.

As soon as he thought of Dongda University, Lin Xiuyi suddenly had a new idea. Is the scope of the investigation a bit conservative? In any case, it should be impossible for a criminal suspect to obtain the victim's new appointment only by meeting once or twice. Because girls like Yano Tomomi and Ninomiya Arisa are not extroverts themselves. It is not easy to open their hearts.

Therefore, there is a necessary condition for the establishment of a suspect, that is, the suspect must have frequent access to the victim. Because only in this way, the suspect can instigate the victim step by step according to his own needs to become a student who dares to engage in theft activities. In this way, the school teachers seem to be more suspicious.

Can a career talk turn an introverted girl into a repeat offender? Anyway, Lin Xiuyi felt that this matter was not so easy.

"Miki, can you focus on investigating all the teachers of Morimura Middle School, whether they are working or resigning, as long as they have taught Yano Tomomi. In addition, I will communicate with Chiba Prefecture and see. Let's see if we can find information on the teachers who taught Arisa Ninomiya back then. After we get the list, we will focus on investigating whether any of these people graduated or studied at Dongda University..."

Lin Xiu picked up the pen and wrote down the results of his analysis with his fingers.

"You still suspect that the murderer is hidden in the teacher, right?"

When Miki heard Lin Xiuyi's order~lightnovelpub.net~, she immediately asked excitedly. Sitting in the office without an investigative idea is too painful. For an activist like Miki, it is absolutely intolerable to sit in the office and wait for clues to come to the door.

"I can't think of anyone other than teachers and classmates who can keep in touch with the victims for a long time and get their new appointments!"

Lin Xiu played with the pen in his hand and said helplessly to Miki.

"Police Department, don't you often say that when all the paths start to fail, the rest of the paths are the right ones? In fact, from the beginning, I felt that the teacher was the most suspicious..."

Miki said proudly. In fact, she had always suspected that the teacher at Moricun School was the murderer she was looking for, but Lin Xiuyi did not investigate in this direction, and Miki, as a subordinate, naturally felt very sorry. To be honest, being able to outperform Lin Xiuyi in some aspects other than physical fitness is something that Miki can't even think about!

"Let's check first, but I don't think there is much hope for teachers to commit crimes, because these teachers can't deter students at all."
